Anyone who has tried a SharePoint tenant migration knows it is not just about moving files. Permissions, folder hierarchy, metadata—all of it has to come along, which is exactly why you need dedicated software instead of manual copy-paste. If you are comparing different migration solutions before choosing one, check out our guide on Tenant-to-Tenant Migration Tools in 2026 for a detailed comparison of the top options. Organizations also need to change environments because of business separation and internal restructuring. As a result, it needs to collect and merge user data and migrate it to the single tenant owned by another organization. Some setups also call for a move of existing data into a new tenant altogether—think mergers, acquisitions, and similar cases. These scenarios demand extra care and careful handling.

SharePoint & Tenant-to-Tenant Migration, Explained

According to Microsoft’s official documentation, we have to review cross-tenant SharePoint migration for supported scenarios and their requirements.

SharePoint	Tenant-to-Tenant
SharePoint is a web-based platform built for teams to store, share & work together securely inside an organization.	A tenant is basically a Microsoft 365 account for any organization.

Why Need to Move SharePoint from One Tenant to Another?

Want a single unified tenant to combine two separate 365 tenant environments.
It is needed when changes occur in business structure or domain name.
Separate the business unit or department from the parent company and make it an independent tenant.
Preserve folder structures, complex data, and sensitive data.
Moreover, schedule the migration task instead of doing it manually.

What Data Can Be Transported from a SharePoint Tenant to Another Tenant?

Some different types of data can be transported:

SharePoint Sites
Files and Folders
List items
Associated Metadata
Version History
Permission access and control

Migrating SharePoint Between Tenants: Where Do You Start?

Option 1: Go, Manual

PowerShell—Microsoft’s built-in tool – is one route people take for this. Admins lean on it to run and automate chunks of the migration, though it’s not exactly beginner-friendly. This route calls for solid technical knowledge, since the source and destination both need separate preparation.

Microsoft’s official documentation provides useful information on planning and managing Microsoft 365 tenant-to-tenant migrations.

There are some steps –

Step 1: Prepare the destination tenant by creating requirement sharepoint sites.

Step 2: Get the necessary PowerShell module set up, and confirm your admin permissions are in order.

Step 3: From here, link up with the source tenant you plan to migrate

Step 4: After that, find the SharePoint sites and review the date on which to start the migration.

Step 5: Then, move the selected SharePoint sites to the destination tenant and perform the migration in batch format.

Step 6: In the last step, check the destination SharePoint content and also check if the user can easily access the data or not.

Drawbacks of the Manual Method

PowerShell requires knowledge of both scripting and SharePoint.	In addition, scripts or commands need to be tested carefully.	Moreover, permissions require additional effort.
Large migrations need batch processing for the migrated data.	As a result, identifying and resolving failed items can take time.	Preserving SharePoint properties may require additional configuration.

Step 5: Fill in the valid credentials and authenticate the source tenant.

Step 6: Run through the same process again, but this time for the destination tenant’s authentication.

Step 7: With that done, line up the source and destination so every user’s data reaches the correct spot.

Frequently Asked Questions

Q1. What is meant by SharePoint cross-tenant migration?

Ans: It is the process of moving SharePoint Online sites, document libraries & metadata from one tenant over to another.

Q2. What happens to permissions once SharePoint data shifts to another tenant?

Ans: Permissions don’t always transfer on their own when data moves to a new tenant. You will likely need to map user accounts to the new setup and double-check access settings afterward.

Q3. Is it safe to move SharePoint Online data between two tenants?

Ans: Yes, it’s safe overall, but it comes down to the method you use. Stick to official, approved methods – if done the wrong way, there’s a real risk of data loss and broken permissions.

Q4. How can large amounts of SharePoint data be moved without a fully manual process?

Ans: For large migrations, you should use the MacSonik tenant-to-tenant migration tool, which can reduce manual work by export multiple files and folders. It also helps with user mapping, filtering, and tracking.

Q5. Can specific SharePoint sites be moved instead of migrating everything?

Ans: Yes, you have the option to pick only the sites you need to move, rather than migrating all the data at once.This selective approach helps reduce unnecessary migration.
